Chrysler sebring 2000 2.5l car wont start!?

I know naturally its a pain to solve some problems on this car. But it cranks over just fine, just won't start. This is what I have tried (2.5L Sebring Conv, 2000)

I Tested 12v on the 2-way pin to the distributor, I have volts.

Tested the pulsing between both CAM/Crank Sensor's, Both are pulsing. However, When the cam pulse's it makes a big buzzing sound, and the Crank pulses are random and pulses 7-10 times when turning the crankshaft by hand. Both pulses are reading 5v. (4.97)

I tested the Ignition Coil Driver (Pin 1 or 6 depends on how you look at it) on the 6-Way Distributor Connection and I am not getting 1.5-2.5V when I try to crank over the engine. The grounds ground the way they should, and I do have good continuity for the ignition coil driver on PCM Connector Pin 4, Just no volts. (Tried testing with wires all together with a paper clip, still no volts.

I have already swapped out the computer (I was guessing the computer was not calculating the timing right) and it did not fix the prob. I check the timing belt, its timing are right.

I tested spark a few diff way, with the distributor cap/rotor on with a wire plugged in, With a plug wire directly in the Ignition Coil Tower, and a few other ways.

I have swapped the ASD Relay out with another one I in the fuse box. I can't find any shorting in any wire I try (That I know of anyway)

SO the crank/cam sensors are working and sending volts to the PCM. I am getting 12v from the ASD relay to my 2-way pin, I am getting pulsing on my fuel injectors, My Cam/crank sensors are toggling 0-5v, Getting 8.7v on the right CAM/Crank wires, The ground on both Cam/Crank are grounding. The only thing I am not getting is Volts on the Ignition Coil Driver.

I did the test with the Ignition key (done test before) And as before it shows me no codes. My code reader for the car also shows me no codes. And the buzzing that happens with the cam, the cam shows 5v for every other full rotation of the engine (I think) It does toggle back and forth 0-5v and when the buzzing happens it only happens or is only noticed when I turn the engine by hand. If you think I have over looked something or I have tested something wrong, please send any test you would like me to do. My car has been not running for a month now and could really use the help.

I am not sure if this will help but heres a link to the all the wireing in the car.

Just the ignition coil driver (PCM 11 was changed in year 1999-2000 car to PCM 4) Thats the only change I know of.

Hope this helps!

Tried almost everything and I am at a lost :(, Please help!%26quot;Chrysler sebring 2000 2.5l car wont start!?Sounds to me like YOU should be answering the questions of others. You've done a great deal to try and figure out the problem.

Their forum is the best when stuff gets this complicated.Chrysler sebring 2000 2.5l car wont start!?Hook it up and scan it. A blk/rd wire is the key. Both spark and fuel drivers are PCM located, if the valve timing and grounds and power are present there may be something wrong with the cam, crank timing. A scanner is used first and mechanical inspections next.
